【 摘 要 】

Fuels and biofuelshave a major importance in the transportation sector of any country, contributingto their economic development. The utilization of these fuels implies theircloser contact to metallic materials, which comprise vehicle, storage, and transportationsystems. Thus, metallic corrosion could be related to fuels and biofuels utilization.Specially, the corrosion associated to gasoline, ethanol, diesel, biodiesel,and their mixtures is discussed in this article. Briefly, the ethanol is themost corrosive and gasoline the least. Few investigations about the effect ofbiodiesel indicate that the corrosion is associated to their unsaturation degreeand the corrosion of diesel is related to its acidity.
